对循经低阻线的形态学研究

<正> 已有研究证明正常人与患者都存在循经低阻线。动物实验也证明大鼠体表和人类相似,其特征是该线上各点的阻抗都较两侧皮肤为低,而且可用其它生物物理学方法加以验证。有人应用普通组织学方法证明循经低阻线皮肤中神经束的数目显著多于对照区。为了进一步研究循经低

MORPHOLOGICAL STUDY ON THE LOW IMPEDANCE LINE ALONG CHANNEL

The occurance of low impedance line(LIL)on the skin surface of both healthy human being and rat has been proved.The characteristics of this line are:1,The impedance of each point on the line is lower and the number of nerve bundles is higher than its adjacent lateral control sides.2,It can be proved by other biophysical methods too.In order to obtain more morphological bases of the LIL,before and after amputation of the extremities of patients the LILs were marked.When the two marked lines were coincident with each other,blocks of tissues including skin together with subcutaneous tissue were cut out and treated with the Farworskys'method.The numbers of nerve bundle,nerve fiber, nerve ending and hair follicle under the LIL and its adjacent lateral sides of 10 patients and 3 rats were counted and compared.It was found that there were more nervous components under the LIL in comparison with its adjacent control area in both patients and rats,but the number of hair follicles was prominently lcss in patients and slightly higher in rats yet without statistic meaning.The results were discussed.
